The Acolyte Unveils Dark Ritual Behind Sith Lightsabers

Star Wars series depicts the sinister process of lightsaber 'bleeding' for the first time on screen.

Lightsaber bleeding involves corrupting kyber crystals with dark emotions.
The Acolyte's finale shows a Sith transforming a Jedi's saber to red.
This process, first seen in comics and novels, is now part of live-action canon.
Kyber crystals resist dark side corruption, making the process dangerous.
Jedi can heal corrupted crystals, turning them white.
